DATING-STAMP.

Specification of Letters Patent.

Patented Jan. 9, 1912.

To all whom it may concern:

Be itknown that I, ELMER H. SANBORN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Dating-Stamps, of which the following is a specification.

This invention relates to improvements in hand stamps and particularly such as are used for applying dates upon letters, papers, etc.

It is the object of the invention to provide a stamp of simple construction which is so date can be readily changed from. day to day and also so that the date upon the impression will always appear in upright position.

It is a further object of the invention to provide such a stamp with an indicator upon the upper side whereby the proper date may be brought into upright position without the necessity of turning the stamp over to discover the relation of the dates.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevation of a stamp constructed in accordance with this invention. Fig. 2 is a central vertical sectional view taken upon the line 22 of Fig. 1. Fig. 3 is a transverse sectional view taken upon the line 3-3 of Fig. 1. Fig. 4 illustrates an impression made by the stamp on the paper or letter to which the stamp may be applied.

The present invention is for a hand stamp which is similar to a stamp, upon which Letters Patent No. 975,463 was granted to me, upon Nov. 15, 1910, and the principal parts of the present invention are like those described and shown in said, patent.

The chief features of said device are shown in the drawing in which 5 represents the bodyportions of the stamp which is usually in the form of a rectangular block. The said block is provided with a central opening or bore 6 in which there is rotatably mounted a sleeve 7. The upper end of the sleeve projects above the block 5 and is formed with a knurled portion by which it may be turned. The under side of the block 5 is formed with a counter-bore 9 providing a seat for an enlarged collar or foot 10 which is formed upon the lower end of the said sleeve 7. In the bore of the sleeve 7 a centrally disposed stem 11 is arranged. The lower end of the stem 11 is formed with an 'terial such as rubber.

enlarged head 12 which is adapted to fit into a counter-bore 13 formed in the lower portion of the sleeve 7, the said counter bore forming a seat for the head 12. The upper end of the stem 11 is formed with a reduced threaded stud 14 which is adapted to receive a handle or knob 15. At the base of the stud 14 an angular or squared neck 16 is formed to receive a similar angular or squared opening 17 which is formed in a yoke or bar 18. The extremities of the yoke are secured to the side faces of the block 5 by fastening devices of any desired type as 19. As indicated in Fig. 1 the portion of the yoke 18 which is formed with the open ing 17 is made horizontal for a short distance, the said yoke being seated upon the upper end of the stem 11 around the neck 16.

The under side of the block 5 is provided with a main ring 20 forming a portion of the stamp and the said ring is rigidly secured to the block as shown in Fig. 2. The said ring is preferably made of elastic ma- The ring is provided with any suitable indications, preferably giving the name and address of the party using the stamp, the impression produced thereby being indicated at 21 in Fig. 4.

The lower end of the sleeve 7 carries a date ring 22 which is rigidly attached to said sleeve and the date ring thus formed is divided upon its lower face with thirty-two equal angular divisions. These divisions are numbered consecutively from one to thirty-one to correspond with the days of the month as indicated at 23 of Fig. 4, and also with a blank or star between one and thirty-one.

The lower face of the head 12 upon the stem 11 carries a central stamp 24., which is permanently attached to said head and bears characters which will print the word paid and any other words which may form a permanent mark of the impressions of the stamp. Adjacent to this central type 24 is a removable type 25 also fastened to r invention to whereby the having dovetailed tongues which are adapted to be received in dovetailed grooves 27, in which they fit, so as to retain the type in printing position. As indicated in Fig. 4 the central stamp bears an arrow or pointer as indicated at 30 which forms a permanent part of the impression of the center stamp and maintains a fixed position with respect to the character on the date ring 22. As shown in said Fig. 4 the date of Feb. 8 is indicated. In order to change the date to the ninth or any other number it is only necessary to grasp the knurled rollersv 8 of the sleeve 7 and to turn the said sleeve slightly so as to rotate the ring 22 to the desired extent, for bringing the proper number opposite the point of the arrow 30.

It will be noted that the stamp constructed as above described will always have the numerals which indicate the date in upright position, to correspond with the position of the central type and the type upon the outer ring 20. The seating of the sleeve 7 in the counter-bore 9 and between the outer block and the head 12 of the stamp 11 affords sufficient frictional contact to hold the said sleeve in any of its adjusted positions.

It is an important feature of the present provide means upon the stamp changing of the dates may be observed without having to turn the stamp upside down. For this purpose a collar or flange 31 is provided upon the said sleeve 7, said collar being secured rigidly upon the sleeve in any desired manner above the block 5 so as to be in plain view and so as to rotate with the sleeve7 when it is turned.

Upon the upper surface of the collar 31,.

numerals are provided which exactly correspond with the numerals upon the ring 22 and are arranged in the same order. 00- operating therewith is a pointer or arrow 32 placed upon the upper surface of the block 5 and the arrangement of the arrow and the numerals upon the collar 31 is such, that when the desired numeral is brought opposite the said arrow 82, the same numerals will be brought opposite the arrow 30 upon the under side of the stem. It-will thus be evident that in it is only necessary to turn the sleeve 7 until the number indicating the proper date is brought opposite the arrow 32, when the stamp will be in readiness for use in stamping the desired date.

What I claim is;

A stamp of the class described having a 2 body portion carrying an outer and inner stamp surface, the inner port1on carrying changing the stamp.

fixed central type having a pointer located 7 thereon, an intermediate stamping face op erating between the outer and inner stamps and carrying dating members adapted to be brought opposite the said pointer, a sleeve movably mounted in the body portion and carrying said intermediate stamping face, 1

a collar upon said sleeve arranged above'the said body portion and having its upper surface exposed to view and formed with dating members corresponding with dates upon the said intermediate member, and a handle adapted to carry the said body portion and the movable sleeve with its intermediate member and indicating collar, the said body portion having a pointer upon its upper surface corresponding with the position of the pointer on the surface of the central stamp.

In witness that I claim the foregoing I have hereunto subscribed my name this 13th day of June, 1911.

ELMER H. SANBORN.
